AIR-TIGHT SEALING DEVICE Foru eANs.

Application filed. August 3, 1926. Serial No. 126,758..

This invention relates to devices for use on top of cans, especiallymilk cans, for the purpose of sealing the ends or openings formed in thecan for inspecting or dispensing the contents thereof.

One of the objects of the invention is to provide a device of thischaracter which will be simple in construction and inexpensive tomanufacture and which will be adapted for use as a permanentattachmentupon top of the can and will, be capable of being readily andeasily operated to perform the desired functions.

Other objects of the invention will appear 5 upon consideration of thefollowing detailed description and accompanying drawing in which: n

Figure 1 is a plan View of the device constructed in accordance with myinvention,

Figure 2 is a longitudinal section through the same,

Figure 3 is a detailed cross section-on the line 33 of Figure 1 andFigure 4 is a cross section taken on the line 4 4- of Figure '1. A

Referring to the drawing by numerals, the can 1, illustrating a milkcan. is provided with the sealed top 2 which is provided withdiametrically opposite punctures or dents 3. These openings are to bescrewthreaded to receive the screwthreaded shank 4 of the fasteningscrews. A sealing band 5 is formed of a strip of metal approximatelyequal in r length to the diameter of the can and this strip is providedat its center wlth a pivot pin 6 fastened to the top of the can, wherebythe sealing band 5 may be swung on the top of the can. Each end of thesealing band 5 is provided with an opening to re-v ceive one of thescrews 4 and washers 7 are interposed between the top of the can and theends of the sealing band 5. The heads 8 of the screws 4: are eachprovided with pintles 9 extending transversely through the heads 8, andthe extended ends of these grips 10 which are adapted to be raised tothe positions shown by dotted lines in Figgrips 10 may then be ofconstruction without piIi-. ties are hingedly connected to the fingerures 3 and 4- whereby they may be used as finger grips in turning thescrews 4. l Vhen the finger grips are not in use, however. they lie flatagainst the sealing band 5 and are held in this position by, fasteningtongues 11 formed of portions ofthe band 5 pressed outwardly therefromand extended through slots or openings 12 in the members 10, where theyare bent as shown to maintain the members 10in position against thesealing band 5.

When the sealin band is to be opened, the tongues 11 will be, bentupwardly so that the finger grips 10 may be swung on their pintles 9. toa vertical position. The finger utilized to turn the screws and removethem'from the screwthreaded openings in the top of the can, whereuponthe sealing band 5 may be swung upon its pivot 6 to expose the openingsor dents 3 in the top of the can.

Minor changes may be made in the details departing from the spirit ofthe invention claims hereunto appended.

What I claim is:

1. A device of the character described or the scope of the v p 6comprising, in combination with a can body having a sealed top, the saidtop being punctured with diametrically opposite openings, the saidopenings being screw threaded, a sealing band extending diametricallyacross the top of the can and pivotally attached to the center thereof,sealing screws carried by the ends of the said band and adapted to bescrewthreadedly mounted in the said openings in. the top of the can, theheads of the 8 said screws being equipped with pintles, and hingedlymounted finger grips mounted on the extended ends of. the said pintles.

2. A device of the character described comprising, in combination with.a can body having a sealed top, the said top being punctured withdiametrically opposite openings, the said openings being screw threaded,a sealing band extending diametrically across the top of the can andpivotally attached to the center thereof, sealing screws carried byfinger grips having openings formed therein, and ineans'onsaid sealingband for releasably holding the said finger grips in inop- 10 V erativepositions. 7
